Don´t use phpBB, because I use SMF. But both are similar and in PHP. Question is, how much is this forum changed from default template. Because after update of code and scripts, it will switch it back to default and you need to change it back. And after another update again.
This is why I´m still gathering strength to update from own forum. Need update from 2.0.2 to 2.0.13.
Don´t remember what all I changed from default.
Because you need make changes in scripts, if you added some new functions not only few graphics changes.
I can understand, why Zac don´t want to do it.
Another thing is, that you need pay for domain and website hosting.
